Efficiency and generalised convexity in vector optimisation problems
Phạm Hữu Sách, Gue Myung Lee, Do Sang Kim · The ANZIAM Journal · 2004
Abstract This paper gives a necessary and sufficient condition for a Kuhn-Tucker point of a non-smooth vector optimisation problem subject to inequality and equality constraints to be an efficient solution. The main tool we use is an alternative theorem which is quite different to a corresponding result by Xu.
